Start here
A display that shows something unexpected is not proof of a board failure. That puts a lock, demo or showroom mode at the top of the list here and a temperature sensor that has drifted at the bottom.
What the machine is doing
- The temperature display drifts by a degree or two over hours — Normal on most cabinets; they show a rolling average rather than an instant reading.
- One compartment ignores its setting entirely — A damper or a sensor specific to that compartment.
- The panel works but the alarm will not clear — The condition is still present, or the alarm needs the door cycled to reset.
- NEAR MISS — the panel is completely dead and nothing runs — That is a no-power fault, and the supply is checked before anything else.
The ranking
- A lock, demo or showroom mode — Every modern cabinet has at least one. First on a cellar cabinet because the whole product is its setpoint: a zone set for reds is doing exactly what it was told while the owner reads it as a fault.
- A damper motor that has lost position — One compartment then runs to its own rules regardless of what the panel is set to. Electronics are checked here because a mode or a lock imitates a dead machine and costs nothing to clear.
- A supply event — a surge, a sag or a brownout — Control boards are the part that remembers a power event. Settings that reset themselves, or a panel that behaves differently after an outage, point straight here. Supply is proved before anything is condemned, because a dead outlet and a dead appliance look identical.
- A temperature sensor that has drifted — A sensor that reads warm makes the unit run forever; one that reads cold makes it stop early.
Check in this order, and why
- Cycle the door open and closed with the alarm sounding — Many alarms need a door cycle to clear once the condition has gone.
- Compare both compartments against thermometers — A single compartment disagreeing points at its damper or its sensor.
- Note whether the code appears at the same time each day — A code tied to the defrost cycle names the system before anyone opens anything.
What to try yourself
- Verify the actual temperature independently — A refrigerator is safe at 40 °F (4 °C) or below.
Tools: thermometer
- Record the code and what the machine physically does — Runs constantly, never runs, runs and stops — that behaviour paired with the code is most of the diagnosis.
- STOP before opening the control housing — Sensors and boards are tested with a meter on live terminals behind a panel. That is where an owner check ends.
Safety
Safety
Control work means working near live terminals, so kill the power at the breaker before opening anything, and remember a stored charge remains after the supply is gone. Treat a temperature alarm as information rather than as a nuisance to be muted.
Where the owner side ends
Call when a code returns after a clean reset, when the display and a thermometer disagree, or when settings will not hold — all three need a meter inside the machine. If the cabinet is warm as well as complaining, treat it as urgent and move the food first.

Scope of this page
Generalized information: this describes the refrigerator class, not your serial number. Anything tied to a chassis — pinouts, part numbers, diagnostic key sequences — is absent by design. A family- or model-level page, where one exists, is linked below and takes precedence. The brand overview page linked below covers the other problems on this machine.
